Lexical Semantic Change Annotation with Large Language Models

AbstractThis paper explores the application of state-of-the-art large language models (LLMs) to the task of lexical semantic change annotation (LSCA) using the historical German DURel dataset. We evaluate five LLMs, and investigate whether retrieval-augmented generation (RAG) with historical encyclopedic knowledge enhances results. Our findings show that the Llama3.3 model achieves comparable performance to GPT-4o despite significant parameter differences, while RAG marginally improves predictions for smaller models but hampers performance for larger ones. Further analysis suggests that our additional context benefits nouns more than verbs and adjectives, demonstrating the nuances of integrating external knowledge for semantic tasks.
